6-284 load data \"Help\"

Hey guys, as mentioned in my other post I am getting ready to have a 6-284 built. I am going to be using a 1-12 twist 30" Krieger, and I will be using 75grn and 87grn V-MAX bullets. I am hoping you guys have some load data for me regarding the 75grn and 87grn V-MAX bullets such as, POWDER, CARTRIDGE OVERALL LENGTH, PRIMER, POWDER CHARGE, VELOCITY. My goal is to get between 3650fps to 3750fps with the 87grn V-MAX and 3850fps to 3950fps with 75grn V-MAX. Let me know what you guys are using and what kind of velocity and accuracy you are getting. I will be using Lupa Brass, and I will be neck turning. My 6-284 will have a tight neck ,272nk. I am also using a Nesika Model K, 1.450 Dia. Action, so I will be able to handle more pressure. I am looking forward to see what you guys have regarding this combination. I went with the 1-12 twist because I want to shoot the lighter weight bullets at high velocity. The guys at Krieger informed me that the 1-12 twist would be perfect for what I was trying to accomplish with this rifle. Thanks guys!!

If it is velocity and Accuracy you want try either IMR-7828 regular or SC and R-22. With a 87gr 3600fps is easy with a 6-284. I was shooting 95 B-tips at 3514fps with 52.5gr of R-22. That load shot in the .1's at 100 and around 1 1/2" at 500 yards. I would start at 52gr with either powder and the 87gr bullet. If you are going to shoot the 75gr then you are going to want a powder like R-19 or Imr-4831. I would start again around 52.5 and work up. Make sure you work up in half grains and use a Chronograph to help tell when you are topping out. Things happen quick pressure wise in this case.

Re: 6-284 load data "Help"

I have never shot light bullets in eather of the 2 that i have had one was a 1-9 and the current one was a 1-8 twist. Mine have always loved 95 or 105 hunting bergers in norma cases and fed 210m. I have had great luck with hoghden 4831sc charges anywere from 48-52.5 and velocitys from 2950 to 3200. Hope it helps. mk

Re: 6-284 load data "Help"

When I first decided to make my 6mm-284 I did some internet searching. I just counted 11 pages of load information I put in my documents. It is really easy to find load data if you are willing to do the search. Most of my data pertained to the 105 and heavier bullets. I posted some lighter bullet loads below. Bet you can find pages of information.

Here are some that apply to your rifle. Just use these as a guide and work up to these listed charges. I have not tried any as I went with 107 sierras and later the 105 Berger target hybrid. Your twist is too slow to take advantage of those higher BC bullets.

Data taken from net:

53.2g of RL-22, CCI BR2 primer, Lapua brass, 87g VMAX seated 0.005 out of the lands. 3598 fps BC for 87 gr is .400
--------
Out of my 6x284 I'm getting 3,630 (Average of 7 shots) with a 87gr V-max. It needs 53.5grs of H4350 to do though.I've only shot coyotes with it and a few squirels ,which I might add turn into a "Red Mist"
-----------------------
I am currently using 49.3g of RL-17 and the 87g VMAX. I am getting 3697 fps +- 4 fps regularly. This powder got me an extra 100 fps (which is the whole point we are shooting this thing!) and the accuracy has been incredible! OF course I am shooting a 30" barrel.
-----------

If you have a borescope you can watch the barrel wear and man it gets ugly when the round count gets to around 750.
